Abstract

A structure for preventing soil pollution by sewage is provided to prevent pollution of rivers and soil by purifying sewage in a water purifier tank firstly and purifying the sewage discharged from the water purifier tank secondly by using filter medium. A water purifier tank(1) is installed to purify sewage generated at factories and houses, and discharged through a sewage pipe(50). A shielding mat(4) is installed at a part where the sewage discharged from a discharge pipe of the water purifier tank drops, to prevent the sewage from infiltrating into soil. An engineering fiber is installed to protect the shielding mat. A first sand layer(6) is accumulated on the engineering fiber for filtering the dropped sewage. Another engineering fiber(7) is installed to filter the sewage passing through the first sand layer, forming a certain space. A carbon filter medium(8) and a plant layer(9) are filled in the space to filter pollutants included in the sewage. A loess and decomposed granite filter medium filters the sewage passing through the carbon filter medium for discharging the filtered sewage to a river(W).

The present invention relates to a structure for preventing soil contamination by wastewater, and more particularly, by directly discharging wastewater discharged from factories, homes, etc. from sewage treatment plants to external streams, thereby preventing pollution of soils around rivers and streams. It relates to the soil pollution prevention structure by waste water.

In general, since sewage and wastewater are generated in factories, homes, etc., sewage or wastewater is treated in a separate sewage treatment plant to be discharged to the stream in order to prevent contamination of the river.

That is, the wastewater generated in the factory is discharged to the stream through the sewage pipe after being treated at the sewage treatment plant, and the sewage is discharged to the river through the sewage pipe at home, which may be buried in the ground as shown in FIG. As well as the sewage pipe 50 extending to the river (W), and is connected to the sewage pipe 50 as well as the connection pipe 51 is connected to the factory or home residential area is composed of a discharge pipe.

However, when the wastewater is discharged directly into the stream through the sewage pipe as described above, wastewater that has not been purified in the sewage treatment plant and sewage at home is absorbed into the soil from the river, causing soil pollution and environmental pollution. .

Accordingly, an object of the present invention is to solve the above problems, it is possible to reduce the environmental pollution by preventing the pollutants from being absorbed into the soil from the river by purifying the waste water when the waste water discharged from the factory and the house flows into the river. The present invention provides a structure for preventing soil contamination by waste water.

In order to realize the above object, the present invention, the septic tank is installed to purify the waste water flowing out of the sewage pipes generated from the factory and the house, and the waste water flowing out of the discharge pipe of the septic tank is disposed in the waste water Mat, which prevents water from penetrating into the soil, geotextiles installed to protect the order mat, and a first sand layer which is laminated on an upper surface of the geotextile fibers and filtered out of waste water flowing out of the discharge pipe, and the aforementioned agent. 1 Geotechnical fibers which are installed to filter wastewater that has passed through the sand layer and arranged to form a predetermined space, and plant layers such as carbon filters and reeds, which are filled in the space to filter pollutants contained in the wastewater, and Ocher masato filtration installed to once again filter wastewater that has passed through a carbon filter It is characterized by consisting of ashes.

1 and 2 is a schematic view showing a structure for preventing soil contamination by waste water according to the present invention and an enlarged view of a filtration unit, and a connection pipe 51 installed so that waste water flows into the sewage pipe 50 from a factory and a house, and It consists of a septic tank (1) installed to purify the waste water flowing through a sewage pipe (50), and the filtration unit (2) for purifying the waste water from the septic tank (1) again before flowing into the stream (W) It is.

That is, once the waste water flowing out of the homes of factories and residential areas is purified in the septic tank 1, the waste water is purified from the filtration unit before flowing into the river W so that the waste water does not flow into the river W. will be.

The filter unit 2 is installed in a portion where the waste water flowing out of the discharge pipe 3 of the septic tank 1 falls so that the waste water does not penetrate into the soil, and the above-described water mat 4 ), A first sand layer (6) laminated on the top surface of the geotextile fiber (5) and the waste water flowing down from the discharge pipe (3) to be filtered off, and the first sand layer described above. Geotextiles (7) installed to filter wastewater that has passed through (6) and formed to form a predetermined space, and carbon filter material (8) and reeds installed to filter contaminants contained in the wastewater by filling in the above spaces It consists of a plant layer (9), such as the ocher omatosato filter material (10) installed to discharge the waste water passing through the carbon filter material (8) once again to the stream (W).

That is, the wastewater falling from the discharge pipe 3 is primarily filtered by the sand filter material 6 and is further filtered by the carbon filter material 8, which exhibits an excellent effect on the adsorption of chemicals. By filtering by (10) to be discharged to the river (W), to prevent the pollutants of the waste water flow into the river (W).

When the pollutants of the waste water are not introduced into the river (W), not only the pollution of the river (W) can be prevented, but the soil can be prevented from being contaminated through the ground of the river (W).

When explaining the effects of the present invention as described above when wastewater is discharged from each factory and home it is collected into the sewage pipe 50 through the connecting pipe 51, the sewage pipe 50 is supplied to the septic tank (1) do.

The waste water supplied to the septic tank 1 is first purified in the septic tank 1 and then discharged to the discharge pipe 3 of the septic tank 1.

The wastewater discharged to the discharge pipe 3 is first filtered through the sand filter material 6, and after the relatively large foreign matters contained in the waste water are removed from the sand filter material 6, the waste water is civil engineering. Passes through the fiber (5) to the carbon filter material (8).

When the wastewater is introduced into the carbon filter material (8), the waste water is purged more cleanly as the chemical is adsorbed therein, and the waste water that has passed through the carbon filter material (8) again flows into the ocher masato filter material (10).

The wastewater introduced into the ocher Masato filtration material 10 flows into the river while being purified by the purifying action of the ocher.

Wastewater flowing into the stream is first purified by sand filter (6), pollutants are filtered by the carbon filter (8), and finally filtered by ocher masato filter (10) Bar (W) is to be introduced, it will be possible to prevent the contamination of the river and soil by the waste water in the factory and home introduced into the river (W).

As described above, the present invention purifies the wastewater discharged from the factory and the home in a septic tank, and also purifies the wastewater discharged from the sand and the soil by sand filter, carbon filter, and yellow clay soil filter. There is an advantage to prevent contamination.
